"Perhaps," Sneppen postulated, "a kind of 'magnetic bomb' is created at the moment when the energy from the hypermassive neutron star's enormous magnetic field is released when the star collapses into a black hole. 2.3 AU is a little more than the distance between the Sun and Mars. Hall thrusters go argon with Starlink V2 mini. Previously, she was a science reporter with a start-up publication called The Academic Times, and before that, was an immunology researcher at Weill Cornell Medical Center in New York. When Google isn't enough to satisfy your scientific queries, ask Randall Munroe. Order here! In any of these scenarios, you'd have to get extraordinarily lucky. More active plate tectonics might be good for life. This is a list of What If? e.g. The CO2 released from the comet would raise the temperature of the Earth for centuries. "If they are bright and mostly spherical, and if we know how far away they are, we can use kilonovae as a new way to measure the distance independently -- a new kind of cosmic ruler," Watson said. This is the same effect you observe when an emergency vehicle passes . Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions, I'd like to remind everyone that while I write sometimes about the interesting physics of bullets, I'm not an authority on firearms safety. Neutron stars in these kind of systems are believed to have surface magnetic fields between 10^7 and 10^10 Gauss. (Stars with higher masses will continue to collapse into stellar-mass black holes.). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. We can use the Doppler effect to measure the orbital motion of a pulsar. Necessary cookies are absolutely essential for the website to function properly. Despite all this, your scenario could fix global warming. Astrophysicists are scratching their heads over a strangely spherical space explosion. [1] People have long suggested that it might be. Using the inverse-square law, we can calculate the radiation dose: Typical properties are shown below. However, a suitably tough baseball glove might be able to snag it. Outer space is a lot higher up than Niagara Falls,[citation needed] so the plunge down into the atmosphere at the bottom of Earth's gravity well adds a lot more than 0.1 degrees worth of heat. Therefore, only the surfaces can cool by the emission of such radiation. We also use third-party cookies that help us analyze and understand how you use this website. Want CNET to notify you of price drops and the latest stories? Okay, if you insist. The largest class of star in the main sequence, these are highly luminous and have life spans measured in only millions of years, rather than the billions or trillions of years for other star types. Okay, so we just need thousands of comets, right? Applying the physicist rule of thumb suggests that the supernova is brighter. Sadly, we don't have the technology to build comet-lowering cranescertainly not in time to help mitigate climate change. This cookie is set by GDPR Cookie Consent plugin. What about our roads and bridges? [2] This means that when a particle accelerator (which produces neutrinos) wants to send a neutrino beam to a detector somewhere else in the world, all it has to do is point the beam at the detectoreven if it's on the other side of the Earth! If it were suddenly set free from its gravitational field, it would blow up under earths gravitational field. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. Inbox, #5, Weird (and Worrying) Questions from the What If? Sure, regular stars can create the basic elements: helium, carbon, neon, oxygen, silicon, and iron. Surface gravity would only have gone up by 0.4%, rather than 1.2%, since surface gravity is proportional to radius. Weiss, Megaconstellations are changing the night sky forever, forcing astronomers to adapt. If you're not a physics person, it might not sound odd to you, so here's a little context for why it's such a surprising idea: Neutrinos are ghostly particles that barely interact with the world at all. book series or on the blog. Neutron stars pack their mass inside a 20-kilometer (12.4 miles) diameter. Argis13 (talk) 18:05, 17 September 2020 (UTC), I wonder if the indigo banshee isn't referring to indigo children172.69.34.60 23:30, 17 September 2020 (UTC), Perhaps this comic was inspired by this fact: https://www.zdnet.com/article/20-years-of-linux-on-big-iron/ The title text is in the style of a Wikipedia page's hatnote / reference note. Explain xkcd: It's 'cause you're dumb. But without it, we go nowhere.\" Carl SaganIf you enjoy What If, make sure to check out our other channel \"Underknown\": https://www.youtube.com/c/interestingshitProduced by Underknown in Toronto, What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. According to a 2016 study, supernovae occurring as close as 50 light-years from Earth could pose an imminent danger to Earths biospherehumans included. This theory was never very widespread,[3]It turns out it's kind of dumb. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! Can a job not hire you because of anxiety? That's why this is a neat question; supernovae are unimaginably huge and neutrinos are unimaginably insubstantial. (, An invention of Randall's, and a reference to the elves of. It's hard to suck in air against the weight of the water, which is why snorkels can only work when your lungs are near the surface. The comet isn't the important part, the crane is. The physicist who mentioned this problem to me told me his rule of thumb for estimating supernova-related numbers: However big you think supernovae are, they're bigger than that. 172.68.24.130 11:02, 30 November 2020 (UTC), No, not really. A neutron star is the remnant of a massive star (bigger than 10 Suns) that has run out of fuel, collapsed, exploded, and collapsed some more. The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. It would just take a lot of patience. [citation needed], I'm thinking a table (Name, appearance, summary, is real?, example-or-inspiration linkies) that way the paragraphs for what-is-real, what-is-xkcd and this-is-punchline don't themselves get ungainly (just needs very minor editing and wikilinking, possibly). You'd have to grab the bullet firmly; otherwise, it might jump out of your hand. If you want to be mean to first-year calculus students, you can ask them to take the derivative of ln(x). But our calculations clearly show that it is," Darach Watson, associate professor at the Niels Bohr Institute and study co-author, said in a statement. If you set the comet on land, it would soak up heat from the atmospherewhich contains much less stored heat than the oceansbriefly cooling the air by an average of one or two thousandths of a degree. Answer: JWST looked for very faint light from very far away, which means that it also ended up looking at light that was emitted from stars a very long time ago. Which would still be less than 1% of the ants in the world. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . Not as quickly as you might think. More details.. What if a tablespoonful of a neutron star was brought to Earth. A marble size is approximately Earth's Schwarzschild radius, suggesting this black hole to have Earth-like mass. 2 is sure to be another instant classic adored by inquisitive readers of all ages. Even after a day, the extra 5.4 kilometers would be handled easily by virtually all structures. Everest. Reminds me of an XKCD joke. Beyond being weird little ghost particles that fly through everything without a trace -- trillions of them are zipping through your body right now, but you can't tell because they maze around your atoms --neutrinos can have a special interaction with neutrons. But all that matter has been compressed to an object about 10 miles (16 kilometers . Large comets can reach the ground intact and be vaporized on impact as their kinetic energy is converted to heat all at once. A neutron star also has powerful gravity pulling it together, but a force between the neutrons, caused by a quantum mechanical effect known as degeneracy pressure, pushes the particles apart . Before publishing the first what if? It explains that during certain supernovae, the collapse of a stellar core into a neutron star, 10 57 neutrinos can be released (one for every proton in the star that collapses to become a neutron). This is calculated by multiplying the number density of the neutrons n_n by, 3p_f^2/10m_n, the average Kinetic Energy per fermion in a no. Filled with bonkers science, boundless curiosity, and Randalls signature stick-figure comics, What If? although it still periodically makes the rounds on YouTube. You get the point. Supernovae[4]"Supernovas" is also fine. When she's not at her desk, she's trying (and failing) to raise her online chess rating. This is a good thing to keep in mind if you buy a digital scale. How long would it take for people to notice their weight gain if the mean radius of the world expanded by 1cm every second? . Blue giant: 2-400 R; 2-300 M, 8000-60000 K, 15-10000000 L. A chunk of ice from space that falls to Earth gains enough energy to warm the ice up, melt it, boil it into vapor, and then heat the vapor to thousands of degrees. The cookie is used to store the user consent for the cookies in the category "Other. Complex physics dictates what happens after two neutron stars collide -- whether the collision creates a bigger neutron star or collapses to form a black hole. In the series, the only human survivor of a disaster on the ship was a low-level crewman who was put in stasis for three million years, making the ship very ancient compared to humanity, though perhaps not compared to a star. This means you're free to copy and share these comics (but not to sell them). When the core of a massive star undergoes gravitational collapse at the end of its life, protons and electrons are literally scrunched together, leaving behind one of nature's most wondrous creations: a neutron star. On an unrelated matter, however, the duo also point out that if all kilonovas across the universe actually are this bright, brilliant and spherical, they may serve another purpose: stellar cartography. [9]Although I wouldn't trust the elevators. Thus, no matter your gun, youre not shooting a bullet around the Earth. Filled with bonkers science, boundless curiosity, and Randall's signature stick-figure comics, What If? For the type of star, see Red dwarf." Lightcaller (talk) 01:55, 17 September 2020 (UTC), Wat. Time is the only remedy for such puzzling cosmic mysteries. [11]Sasselov, Dimitar D.. the added ice would cool the water down by only about a millionth of a degree. Mount Thor, which you may remember from question #51, features a vertical drop of 1,250 meters. After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. Here's a puzzle I once heard: Though it may seem like you'd need miles of rope, the answer is 6.28 meters. What If? 125. While a normal black hole has the mass of 9.945e+30 (five times the sun. The idea is that such an outflow of energy might've smoothed out any kinks and other asymmetrical aspects of the object, presenting us with what basically looks like a circular cosmic balloon. A blur, mostly. 08.23.07. Is there any way to fire a gun so that the bullet flies through the air and can then be safely caught by hand? 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! At this point, even the strongest humans would only be able to walk with great difficulty. More massive stars explode as supernovas, while their cores collapse into neutron stars: ultra-dense, fast-spinning spheres made of the same ingredients as the nucleus of an atom. A giant star faces several possible fates when it dies in a supernova. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. How do I move data from one tab to another in Excel? As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. Everest would no longer be in the "death zone". A stone si. At that speed, as long as you were in the right place at the right time, you could snatch it out of the air. \[ x=0.00001118\text{ parsecs}=2.3\text{ AU} \] If the article has a different name in the corresponding book than on the blog, then the alternative title will be listed alongside the blog title. Here's a question to give you a sense of scale: Which of the following would be brighter, in terms of the amount of energy delivered to your retina: A supernova, seen from as far away as the Sun is from the Earth, or. Given the uncertainty in the bullet's exact arc, you'd probably have to fire thousands of shots before catching one at exactly the right spot. Hercules X-1 isn't alone in space. :) NiceGuy1 (talk) 03:54, 26 September 2021 (UTC), Let me know what you think. If it comes down to a vote, I think that we should stick with American spelling in general, because Randall is American. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. This Neutron Star Explosion Was Perfect. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. Plate tectonics play a key role in stabilizing the Earth's climate, and planets smaller than Earth (like Mars) don't have enough internal heat to sustain long-term geologic activity. The reason you don't notice the neutrino flood is that neutrinos hardly interact with ordinary matter at all. Anybody know why? where m is the mass of the neutron and h is Planck's constant. 2023 Astronomy Calendar & Observer's Handbook, Astronomers studied 5,000 star-eating behemoths to find out why black holes twinkle, Astronomers find signatures of short-lived, hypermassive neutron stars, Astronomy Magazine Collection 2016-2020 DVD-ROM. Each one will cool the air a little bit. His stick-figure drawings about science, technology, language, and love have an enormous, dedicated following, as do his deeply researched answers to his fans' strangest questions. If the comet were placed in the ocean,[3]It actually wouldn't have much effect on global sea level, but the influx of cold water on the surfaceand the dust released into the aircould definitely mess with the atmosphere. Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. If you weighed 70 kg when the expansion started, you'd weigh 88 kg now. Unfazed by absurdity, Randall consults the latest research on everything from swing-set physics to airplane-catapult design to clearly and concisely answer his readers questions. While you might not notice the increased gravity just yet, you'd notice the expansion. But if you can't handle me at my worst, then you sure as hell don't deserve me at my best.". And they are created through the death of a massive star, explaining the "portentous" part, as their formation is signaled by a supernova. Death from Above. Neutron stars typically have a radius of 10 km / 6.2 mi and a mass of around 1.4 to 3.2 solar masses. After 10 years, gravity would be 50% stronger. Health Physics 82, no. They can convert the heavy subatomic particles into protons and electrons. . Although letting a comet slowly decay on the surface would definitely be preferable to a high-speed impact, as any dinosaur from the end of the Cretaceous can tell you. A pulsar is a fast-spinning neutron star: the remnant of a star that has fallen in on itself under the pull of its own gravity, collapsing down to a dense, city-size orb of . Monisha Ravisetti. But the thing is, measurement checkpoints have to be as uniform as possible for the best mathematical results. Less often if you're a child, since you have fewer atoms to be hit. is based on his blog of the same name that answers unusual science questions from readers in a light-hearted way that is scientifically grounded. So while you could lift a spoonful of Sun, you cant lift a spoonful of neutron star. The neutron star, known as PSR J0952-0607, was discovered in 2017 about . [2]I'd like to remind everyone that while I write sometimes about the interesting physics of bullets, I'm not an authority on firearms safety. At the start of the scenario, the entire Earths population has been magically transported together into one place. A spherical explosion [provides] much greater precision in the measurement.". I've seen quite a bit of that on this page. The dynamics of really huge rocky planets aren't often analyzed, since there's no obvious way that they could form; anything that large will have enough gravity to gather hydrogen and helium during planet formation and become a gas giant. They are responsible for, A real star type. articles, published either in Randall Munroe's What If? Want to know what would happen if you rode a helicopter blade, built a billion-story building, made a lava lamp out of lava, or jumped on a geyser as it erupted? Bottom line: Neutron stars are the collapsed cores of formerly massive stars that have been crushed to an extreme density by supernova explosions. At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . How long should I wait to text after being left on read? [1] But under the right conditions, you could catch a bullet. What If? This heat energy would be about 100 times greater than the energy needed to bring even a very cold comet up to room temperature, so a comet falling from space would heat the Earth 100 times more than it cooled it. After this point, it would collapse into something like a sputtering white dwarf or neutron star, and thenif its mass kept increasingeventually become a black hole. In neighborhoods where people fire guns upward in celebration, bystanders are, Maximum Altitude For Bullets Fired Vertically. Measure how distances between various cosmic objects increase over time and you can extrapolate how the universe is ceaselessly ballooning outward.

How do I get rid of whiteheads on my nose naturally? 2023 CNET, a Red Ventures company. Eventually, they would have to break up, right? astronomy. The very central region of the star the core collapses, crushing together every proton and electron into a neutron. The nature of matter under these conditions is a decades-old unsolved problem. How do you prevent jellyfish stings when swimming? GPS timing is incredibly precise; of all the problems in engineering, it's one of the only ones in which engineers have been forced to include both special and general relativity in their calculations. A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? Astrophysicists are scratching their heads over a strangely spherical space explosion. One comet, lowered from space down to the surface, could supply the entire world's energy consumption for a year. 2 is sure to be another instant classic adored by inquisitive readers of all ages. What If? [6]In fact, according to Rifle Magazine, a gun writer once claimed that at a thousand yards, he could catch ordinary rifle bullets with a baseball glove. Most of our infrastructure would have collapsed. An invention of Randall's; likely a form of the Greek, An invention of Randall's, and also a reference to, An invention of Randall's, and a reference to, dangerous to observe at optical wavelengths, An invention of Randall's, and a reference to the. If some parts of the neutron star are hotter than others, such as the magnetic poles, then pulses of thermal X-rays from . The Only! They are extremely dense and no longer undergo nuclear fusion. It no longer burns hydrogen, helium . View our Privacy Policy. Red dwarf: 0.09-0.5 R; 0.07-0.3 M, 1500-4000 K, 0.00001-0.05 L. If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. #HowTheUniverseWorksA neutron star is one of the most dangerous objects in the universe. As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. Magical storks deliver babies, magical cranes deliver comets. would change Earth's radiation balance, trapping heat near the surface and raising the planet's temperature. So unless you stood right next to the spoon, you wouldnt notice. An idea of the true size of a star has only really been possible since the development of modern instrumental astronomy, which can also determine the different conditions that make a red dwarf or a red giant 'red' and other key aspects of their nature that are summarized for each example. Crops wouldn't stand up under their own weight. Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions. Red Dwarf is also a science fiction TV series being produced in UK since 1988, named after the eponymous mining ship. Concrete expands and contracts by more than that every day. :P 172.69.63.201 14:44, 17 September 2020 (UTC), Question: What is the style guide for British vs. American Spelling (e.g., Color vs. Colour) in explain xkcd? Inbox, #8, Weird (and Worrying) Questions from the What If? It makes no sense that it is spherical, like a ball. Breathing in this situation would be difficult.
